IMPROVEMENT IN PEA-NUT THRASHERS AND SEPARATDRS.

Specification forming part of Letters Patent No. 127,392, dated May 28, 1872.

A represents the thrasher, B the endless carrier, and O the separator. D is a revolving cylinder of diagonally-crossed wires d,.which work against a concave, E, correspondingly constructed. The cylinder D is also provided with longitudinal wires d, which work in concave E may be adjusted closer to or remote from the cylinder D. b is a rigid trough ar ranged beneath the concave E, and over which moves the endless carrier-belt b. The separator 0 consists of an open-work cylinder, 0, formed of straight longitudinal slats 0 with intervals between them smaller than a peanut, and of transverse screens 0 sufficiently coarse to allow the pea-nuts to pass readily therethrough. The cylinderdeclines forward, so as to cause the movable peanuts to gradually find their way out at the open end. i

The mode of operation is as follows: The vines, filled with pea-nuts, are pushed down the incline 9 until they are caught by the revolving cylinder D. The reticulated surfaces of cylinder and concave thrash and tear the vines to pieces and separate the nuts from them. The bulk of the vines are carried up and on the other side of cylinder by the longitudinal wires d, and then are removed by the revolving wires f from the machine. The remaining bitsof vine and the nuts fall into trough b and on the endless carrier 1), by which they are transferred to the separator G. As soon as they reach the open-work and revolving cylinder 0 the bits of vine and the smaller nuts begin to pass through the spaces between slats c and, as they are arrested by the coarse transverse screen-partitions 0 c become effectually separated from the large and merchantable nuts, which themselves pass onto the end and fall into some receptacle there prepared for them.

By this machine the nuts can be thrashed, cleaned, and prepared for market :at a small cost and with great economy of time.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of a cylinder, .D, consisting of diagonal wires d and longitudinal wires 01, with a wire concave, E, as and for the purpose described.

2. The revolving longitudinal wires f, combined with the revolving cylinder D d 01, constructed as described, as and for the purpose specified.

3. In combination with the concave E, the
